Greater productive output for steel and cast iron machining

The Tiger·tec Silver series offers a reliable balance between wear resistance and toughness. With its WKP35S coated carbide grade, the insert delivers consistent cutting performance when machining steel and cast iron, reducing unplanned tool changes and downtime. The coating improves thermal stability at elevated cutting temperatures, which in practice means more uninterrupted production time and predictable tool life. For manufacturing managers, this translates into measurable efficiency gains on series runs.

Coating and grade that extend tool life and reduce costs

The combination of a modern coating technology and a purpose‑designed grade provides superior resistance to abrasive wear while preserving a robust cutting edge. The coated carbide construction reduces flank and crater wear, so edge integrity is maintained over longer cycles. As a result, the insert helps contain tooling costs through extended intervals between indexings and replacements, supporting a lower cost per component without compromising surface finish or dimensional control.

Geometry engineered for stable chip control and secure process behaviour

The chipbreaker 7R‑E67 and the insert geometry are tailored to promote predictable chip formation under varying feed and speed conditions. Stable chip control reduces the risk of chip entanglement and improves evacuation from the cutting zone, which is particularly relevant when working with cast iron where chips tend to be shorter and more abrasive. The resulting process stability enhances overall machining reliability and supports repeatable part quality across shift cycles.

Practical integration and application guidance for shop use

The insert is designed for straightforward integration into standard drilling and boring toolholders. While the designation indicates its primary function, the geometry and grade allow flexible use across different cutting regimes typical in small‑ to medium‑batch production. For teams less familiar with coated carbide grades, note that a few incremental adjustments to cutting speed and feed—guided by the grade’s thermal and wear characteristics—will unlock the best balance between tool life and component finish.
